A new low-reynolds-number k-ϵ model for turbulent flow over smooth and rough surfaces
Date of Original Version
A new low-Reynolds-number k-ϵ model is proposed to simulate turbulent flow over smooth and rough surfaces by including the equivalent sand-grain roughness height into the model functions. The simulation of various flow experiments shows that the model can predict the log-law velocity profile and other properties such as friction factors, turbulent kinetic energy and dissipation rate for both smooth and rough surfaces. © 1996 by ASME.
